What Is a False Dichotomy? | Definition & Examples

Reasoning updated on  March 18, 2024 4 min read

A false dichotomy occurs when someone falsely frames an issue as having only two options even though more possibilities exist.

This oversimplification can lead people to overlook valid alternatives, believing they must choose between the two extreme options.

False dichotomy example
“If you don’t support economic sanctions against Country A, you must support its oppressive regime.”

This is an example of a false dichotomy because it oversimplifies a complex scenario and claims there are only two possible stances. In reality, it is possible to have a more nuanced position or support neither option.

What is a false dichotomy?

A false dichotomy is a logical fallacy in which only two possibilities, typically extreme opposites, are presented in a situation that requires greater nuance. It is also known as the either-or fallacy or the false dilemma fallacy.

False dichotomies are often used intentionally in persuasive communication. By misleading audiences into thinking only two options exist, people such as politicians and marketers can easily influence people’s opinions and decisions.

The false dichotomy fallacy is an informal logical fallacy, meaning that it’s an error of content rather than structure.

False dichotomy fallacies can also be categorized as fallacies of presumption, which are arguments that assume the truth of something that has not been proven. There are several other fallacies of presumption, including the following:

  • Circular reasoning fallacy: Using the conclusion as a premise, essentially saying the same thing twice in different words without proving it
  • Begging the question fallacy: Subtly assuming the conclusion’s truth within the argument’s premises and failing to provide necessary evidence
  • Loaded question fallacy: Asking a question that contains an assumption, which if answered, implies agreement with the assumption
  • Complex question fallacy: Asking a question that presupposes a particular answer by embedding it within the question

False dichotomy examples

Examples of false dichotomies can be found in various domains, such as politics, philosophy, and everyday conversations.

False dichotomy example in real life
A finance professor offers career advice to students: “Either pursue a high-paying job or follow your passion; you can’t have both.”

This advice exemplifies a false dichotomy by simplifying a complex decision into a binary choice between career satisfaction and financial success. The professor’s statement assumes that it’s impossible to achieve both personal fulfillment and a lucrative income.

False dichotomies can be used effectively in advertising because they pressure the audience to limit their thinking to two simple choices. Typically one option is extremely positive and the other extremely negative.

False dichotomy example in advertising
An ad for a weight loss program includes the following claim: “You can either stay overweight or transform your life with our program.”

The choice between being overweight and using this specific product is an example of a false dichotomy. In reality, there are many options other than the two mentioned, such as losing weight independently or using a different program.

Similarly, false dichotomies can be used in various types of entertainment and news media to present an issue in a sensationalistic way and garner attention.

Media professionals use this technique, knowing they can attract more viewers and readers with extreme statements than they would by using more reasonable language.

False dichotomy example in media
A headline from a technology news magazine reads, “Will AI be our savior or the end of humanity?”

This headline presents a false dichotomy by claiming that AI can only have an incredibly positive or extremely negative effect on society. This false framing ignores the more likely possibility that AI will be used in ways that present a combination of advantages and challenges.

Why are false dichotomy fallacies effective?

People tend to commit and be persuaded by false dichotomy fallacies primarily because of cognitive biases, which are common patterns of reasoning errors. Two cognitive biases are particularly relevant to the false dichotomy fallacy:

  • Black-and-white thinking: A tendency to see things in absolute terms and oversimplify rather than recognize nuance
  • Confirmation bias: A predisposition to seek and remember information that confirms existing beliefs, including oversimplified representations of complex issues

How can you avoid false dichotomies?

Avoiding the false dichotomy fallacy involves being skeptical of any simplistic representation of an issue that is fairly complicated.

These strategies can help you avoid committing or being misled by the false dichotomy fallacy:

  • Recognize oversimplification: Make a habit of noticing when only two extreme options are presented, which is often a sign of reductive thinking.
  • Seek and include alternatives: Search for additional options beyond the most obvious possibilities, and include them in your argument.
  • Accurately convey complexity: Ensure that your argument captures an issue’s nuances as honestly and precisely as possible.

What does dichotomy mean?

The word “dichotomy” refers to a division or contrast between two things that are (or are represented as being) opposed or entirely different.

The false dichotomy fallacy occurs when someone presents a situation as having only two possible outcomes or options when there are more alternatives available.

Can a dichotomy be legitimate?

Dichotomies are valid when, considering all scenarios, only two options are indeed possible.

Here are some examples of legitimate dichotomies:

  • On or off (electricity)
  • Present or absent
  • Living or dead

Here is an example of how the word “dichotomy” can be used accurately in a sentence:

“The professor discussed the dichotomy between living and non-living entities, teaching students to distinguish between organisms that exhibit all characteristics of life and those that do not.”

The false dichotomy fallacy occurs when an issue is presented as if it had only two mutually exclusive possibilities, even though it is actually more complex.

What are the alternative names for the false dichotomy fallacy?

The false dichotomy fallacy is also known as the false dilemma fallacy or the either-or fallacy.
